Modern Xiaomi smartphones, powered by MIUI or the new HyperOS, offer users a wide range of media management capabilities, and peripheral connectivity is key. Wireless headphones or headsets have become an integral part of everyday life, allowing you to enjoy high-quality music during training or take important calls without being distracted. The interface process in the Android ecosystem is usually as simple as possible, but owners of Xiaomi, Redmi and Poco devices sometimes face nuances that require a deeper understanding of system settings.
In this article, we will take a look at all the steps of connection, from basic activation of the module to fine-tuning audio codecs to achieve studio sound quality. You will learn how to correctly put the headset in detection mode, what to do if the device is not visible in the list of available, and how to optimize the Bluetooth for games or listening to Lossless audio. Understanding these processes will help you avoid typical errors and fully unlock the potential of your audio equipment in conjunction with a smartphone.
It is worth noting that the algorithms of Bluetooth in different versions of the operating system may differ slightly visually, but the logic of actions remains the same for the entire model range of the brand. We will consider universal methods that are suitable for both the flagship models of the Mi and Xiaomi series, and for the budget lines of the Redmi Note.
Preparation of the headset and smartphone for pairing
Before you go to software settings, you need to ensure that both devices are physically ready for communication. The wireless headset needs to be charged, because at low charge, some models may not go into active search or work unstable. If you use the device for the first time, be sure to remove protective films from the charging contact areas, if any.
Special attention should be paid to pairing mode, as this is the most common cause of problems for beginners. Just turning on headphones is often not enough – they must go to a state where they are visible to all surrounding devices. In most models, this requires pressing the power button or a special function key for 5-7 seconds until the indicator begins to flash blue or alternately blue and red.
⚠️ Warning: If the headset light flashes white quickly or burns constantly, it could mean it’s already connected to another device.In this case, turn off Bluetooth on the tablet or laptop it was previously tied to, otherwise the Xiaomi phone will not be able to find the accessory.
For your smartphone, make sure the screen is unlocked and you are in line of sight with a headset, ideally no more than 1 meter away. The presence of interference in the form of working microwave ovens or powerful Wi-Fi routers in the immediate vicinity can temporarily worsen the quality of search, so if you have difficulties, you should move to another place.
- 🎧 Charge the headset to a level of at least 30-40% for stable operation during the setup.
- 📱 Unlock the screen of Xiaomi smartphone and make sure that it does not run heavy applications that consume processor resources.
- 🔦 Check the indication on the headphones: Search mode is usually characterized by slow or fast flashing of LEDs.
Bluetooth activation and device search in MIUI and HyperOS
The process of turning on the wireless module in Xiaomi smartphones is standardized, but has its own features depending on the version of the interface. The fastest way is to use the control panel, which is called by swipe down from the top of the screen. In the expanded curtain menu, you need to find the icon with the Bluetooth logo and activate it. If the icon is not on the first screen, swipe left to open additional pages, or click on a pencil to edit the panel.
For more in-depth customization and guaranteed detection of all devices, you’d better go to the full system settings menu. To do this, open the Settings app and select the Bluetooth section. In some versions of MIUI, this item may be inside the Connection and Sharing category. Once you go to the menu, the system will automatically start scanning the surrounding space.
It is important to understand the difference between the states of the module: when it is just on, the phone may be invisible to others, but look for the devices yourself. The moment you are in the Bluetooth menu, the Xiaomi smartphone becomes visible for pairing, which is displayed by the corresponding status called the phone model. If the list of available devices is empty, click on the update button or wait a few seconds, as the scan is cyclical.
Owners of new HyperOS models may notice a redesigned interface, where available devices are grouped into categories: Audio, Wearable, Auto. This makes navigation easier, but the principle of operation remains the same.
Step-by-step instructions for connecting the headset
Once the module is activated and the headset is in search mode, a list of available devices should appear on the smartphone screen. Find the name of your model in the list, which usually corresponds to the brand or headphone model (for example, JBL Tune, Sony WH, Xiaomi Buds).
The system may request confirmation of action or input PIN-In most modern cases, the code is not required and the connection is established automatically. However, if the request appears, the standard combinations are most often 0000 or 1234.
☑️ Connection algorithm
When you successfully connect, you'll hear a distinctive audio signal in your headphones, and on your phone screen, the status will change to "Connected" or "Used for calls and audio." At the same time, an icon will appear in the top status bar. If the Xiaomi ecosystem device connects, an animated window with the image of the headphones and the level of charge of their batteries may appear on the screen.
⚠️ Warning: If after clicking on the device in the list, the status hangs on "Conjugation..." and after a while gives an error, do not try to press the button again indefinitely.
Sometimes the system offers to configure additional functions, such as voice assistant or gesture control, if the headset supports these options and has the appropriate application.
Customization of sound quality and audio codecs
For audiophiles and owners of high-quality acoustics, standard settings may not be enough. Xiaomi smartphones support various audio transmission protocols such as SBC, AAC, aptX, LDAC or LHDC. By default, the system chooses the most compatible codec, but you can force it to change it to improve quality or reduce latency.
To access these settings, you need to activate the developer menu. Go to Settings → About Phone and quickly click 7 times on MIUI Version or OS Version. Once you have become a developer, go back to the main settings menu, select Advanced Settings → For Developers. In this list, find the Bluetooth-related section and select the Bluetooth Codec.
| Codec | Sound quality | Delay (Latency) | Compatibility |
|---|---|---|---|
| SBC | Basic | Tall. | All devices. |
| AAC | Good. | Medium | iOS, Android |
| aptX HD | High. | Low. | Qualcomm |
| LDAC/LHDC | Hi-Res (Studio) | Medium/High | Flagships |
When choosing a codec, consider the capabilities of your headset. If the headphones do not support LDAC, choosing this codec in the phone settings will either not work or will cause interruption of the sound. For games, it is recommended to choose low-latency codecs (for example, aptX Low Latency, if available), and for music, high-bitrate codecs.
What is a bitrate and why is it important?
You can also find the option “Switch off absolute volume” on the developer menu. If you notice that the volume of the headphones and phone is not synchronized (for example, on the phone at most, and in the headphones is quiet), turning on or off this option can solve the problem of desynchronizing levels.
Connected Device Management and Priorities
In the Bluetooth menu of Xiaomi smartphone, you can control already paired devices. By clicking on the gear icon or arrow next to the headset name, you are taken to the device card. This displays the charge level (if supported by the protocol), the mac address and the use profile switches: Media Sound, Call Sound, Incoming Calls.
One of the useful features is the ability to turn off certain profiles. For example, you can leave the headset connected for notifications, but you can prevent the transmission of media sound so that the music plays through the phone speaker and the navigator speaks into headphones.
If you have multiple devices connected to your phone (like a smartwatch and headphones), the system automatically distributes the streams. However, the priority of the sound often depends on which application was launched last. You can manually switch the output by opening the volume control panel (volume buttons) and selecting the desired device in the drop-down list above the slider.
- 🔊 Media Sound is responsible for music, video and games.
- 📞 Profile "Call Sound" transmits the voice of the interlocutor during a telephone conversation.
- 🔔 Disabling profiles helps save battery life if full functionality is not required.
Solution: Headset is not connected or is working intermittently
Despite the stability of Android, there are times when the headset doesn't work properly. If the device doesn't connect, try Forget the Device in the Bluetooth menu and pair it again, which clears old encryption keys that may have been corrupted.
Intermittent sound or stuttering problems are often associated with channel overload or physical obstacles. Make sure there are no thick walls or metal structures between the phone and the headphones. It’s also worth checking if the developer’s settings include “Enable HW Profile Overheads,” which sometimes conflicts with the stability of the connection on certain chips.
💡
If the sound in the headphones has become quiet or gone, try clearing the Bluetooth cache through the application menu. Find in the list of system applications "Bluetooth", go to the storage and click "Clear cache", then restart the phone.
In rare cases, the problem is energy saving. MIUI is known for its aggressive optimization that can kill Bluetooth background processes. Go to the battery settings, find the application you're listening to music through (such as a player or browser), and set the energy saving mode to "No restrictions".
⚠️ Note: Network Reset removes all stored Wi-Fi passwords and Bluetooth pairings. Use this option only as a last resort when other methods have not worked, and be prepared to re-enter passwords from home networks.
If nothing helps, check the compatibility of Bluetooth versions. Connecting a Bluetooth 2.0 device to a Bluetooth 5.0 phone is possible, but the functionality will be limited by the old headset. In such cases, updating the firmware of the headphones themselves through the manufacturer's proprietary application often works wonders.
